Ionic inAppBrowser executeScript gives "Uncaught EvalError: Refused to evaluate a string as JavaScript because 'unsafe-eval' is not an allowed source"

Question

Update 25/6/23:

I went back to a previous version of my app and this works, so it's clearly something that I've changed in the last 6 months.

Original:

When I try to call executeScript on a Twitter page I've opened in Ionic's @ionic-native/in-app-browser on an Android emulator I get this error from that webpage:

Uncaught EvalError: Refused to evaluate a string as JavaScript because 'unsafe-eval' is not an allowed source of script in the following Content Security Policy directive: "script-src 'self' 'unsafe-inline' <and then some url's with wildcards which SO won't let me include in my question>".

I am trying to open the page like this:

options = "location=yes,closebuttoncaption=" + buttonWording + ",usewkwebview=yes";
this.browserpopup = this.iab.create(this.temp_selected_link, '_blank', options);
this.browserpopup.on('loadstop').subscribe(event => {
      console.log('loadstop: event = ', event);
      console.log('About to call: this.browserpopup.executeScript');
      this.browserpopup.executeScript({
        code: "(function myFunction() { setTimeout(myFunction, 1000); const returnObject = {'url': '' } returnObject.url = window.location.href; return returnObject;} )()"
// I've cut down the code for brevity
      }, (returnObject) => {
        this.returnObject = returnObject;
        console.log('loadstop: returnObject = ', returnObject);
      })
    });

I am expecting returnObject to log to the console every second. Instead I get the error above logged every second.

This works with other web pages, but Twitter throws this error.

It has worked with Twitter in the past, but I guess they have changed their CSP policy.

I've tried calling executeScript on a window.open object, as per this issue but then I get an error that executeScript is not a function of window.
